Patent DE-4008949-A1 (DE)
Title: Dual-purpose label for use as tag and self-adhesive label - comprises thin label layer with low bending stiffness and removable backing layer with high tear resistance and stiffness
Inventor: STRAUSS NORBERT
IPC: G09F3/04
Filed: 1990-03-20
Abstract: A dual-purpose label, is used both as a tag and as a self-adhesive label, is required to adhere to both curved as well as flat surfaces and therefore has a low bending stiffness. Suitable materials generally have low tear resistance which causes rapid failure of a hole in the label when used as a tag. A covering material is used to act as a reinforcing layer and the combined layers provide high tear resistance at the hole and sufficiently low bending stiffness after cover removal prior to attachment to curved surfaces. The label material comprises a relatively thin material, pref. oriented PP or PETP film. A suitable cover material consists of PP or PVC film, pref. an impact modified rigid PVC film. USE/ADVANTAGE - The label is used both as a self-adhesive label and as a tag suspended by a cord through a hole, has high hole tear strength and bending stiffness for the latter purpose and low-bending stiffness for the former.

Patent DE-4110400-A1 (DE)
Inventor: LUHN ACHIM DR
IPC: H04N19/90
Filed: 1991-03-28
Abstract: Images are approximated by invariant densities of stochastic processes, for example by so-called fractals. The parameters of such stochastic process whose invariant densities optimally approximate the images to be compressed, according to a quality criterion, produce a compressed reproduction of the image. The optimal stochastic processes are found by means of a stochastic optimization process, preferably by means of a genetic optimization process that uses, among others, mutation, cross-over and exchange of genes in order to change genetic information. This process allows extraordinarily high data compression factors to be obtained, typically between 1000 and 10000. This process is suitable for data compression of still images as well as for the compression of images formed of moving image sequences.

In each case, the other high pressure pipe is connected to a leak oil connection. A connecting channel (10) is provided between the pressure chambers (9a,9b) of the first and second valve needles, and through which, during the fuel injection process, fuel to be injected flows from the valve needle not in operation to that which is active.

Title: Combustion system for alternate gases - keeps flow-regulator settings at constant ratio to each other
Inventor: HOERNER HUBERT
IPC: F23K5/00
Filed: 1991-05-23
Abstract: The combustion system is for gases of different compositions in a burner, these being delivered alternately to it with their flow rates regulated so as to give a constant enthalpy current.
